Fluorite has a wide variety of uses. The primary uses are in the metallurgical, ceramics, and chemical industries; however, optical, lapidary, and other uses are also important. Fluorspar, the name used for fluorite when it is sold as a bulk material or in processed form, is sold in three different grades (acid, ceramic, and metallurgical).

This requires an average anion radius which must be determined considering any anion vacancies in the disordered fluorite structure. In an ideal fluorite structure (i.e., MX 2), the average anion radius coincides with the actual anion radius because all anion positions are occupied.This changes for anion-deficient fluorite structures because the …

Combinations of …

Fluorite crystal carries in its wonderfully intricate designs the spiritual qualities of symmetry, beauty, lucid dreams, and even genius.
